40+5=45 is written in extended form so your answer is 45
P=44+66+88/2=198/2=99
With Heron formula:
S=root 99*(99-44)(99-66)(99-88)=root 99*55*33*11=root 1976535= 1405.8929.....=1405.9
The value of angle x is 127 degrees.
<h3>How to find angles?</h3>
The angle x can be found as follows:
Angle on a straight line is 180 degrees.
Therefore, the sum of 53 degrees and x degrees is 180 degrees.
Therefore,
53 + x = 180°(sum of angles on a straight line)
subtract 53 from both sides of the equation
53 - 53 + x = 180 - 53
x = 127°
Therefore, the angle of x is 127 degrees.

Answer:
156 cm^2
Step-by-step explanation:
area of a paralelogram is Base times hieght
13 times 12
We have question
<span> /*8 (multiply both sides by 8)</span>
/*6 (multiply both sides by 6)
/-30 both sides
8W=-66-30
8W=-96
W=-12
